so if f(x) = 0 at x = 3,+/- 2i.
what is the f(x) factored form
=x^2(x-3)+4(x-3) Not true
That would be
x^3 - 3x^2 + 4x - 12
You have told me that the zeros of the function are:
Therefore the factored form is:
try multiplying that out
x^3 - 3 x^2 + 4x -12
so I think you have a typo in your opening line
where is the typo in which opening line? And I believe I used the wrong symbol for the factored function it's suppose to be a plus sign over a __ but I can't figure how to type this. and maybe that's what is giving us the answer you have given me. Could that be it? and that is not -12, negative 12 it's minus 12
